My DD is adopted. Baby adoption (she was 16 months when we got our adoption order, she was in the same foster from birth with a lovely older couple). She's 11 now, and shes a beautiful, amazing girl. My whole world.
There was no background of drugs or alcohol. Her birth family had a chaotic/nomadic lifestyle, and it was deemed very early in the pregnancy that she would be at risk (birth parent had already had a child taken into care). Birth parents opposed her being adopted in the sense that they refused to sign anything, but made no actual effort beyond that to oppose. She could have been with us sooner had they agreed.
When we applied to adopt, we requested age 2 years and upwards, because we thought babies were an extreme rarity. We were quickly persuaded (for a few reasons, our age was one factor - both of us well under 40) to amend our application to baby adoption. We were told that there WERE, contrary to belief, not insignificant numbers of babies requiring adoption. During home study, we said no to most things (you are asked what history you feel able to cope with). We realised that we were limiting ourselves, but it wouldve been unfair to agree to things we knew we couldnt deal with.
The process IS as gruelling as people say. I think time scales have changed now to shorten the approval process, but I imagine the criteria is still as strict. We went on an introduction course, and there were several couples and single people, however only us and one other couple made it to approval.
I think we were lucky in a few senses. We live in a small coastal town, we had a very experienced social work 'elder' conducting our home study (she was shit hot tbf, really took us under her wing) and we had no criteria issues. Our daughter is also perhaps something of a rarity (though perhaps not as much as people think, babies ARE still sometimes relinquished) in her background. That said, she still had to cope with leaving her beloved foster carers at a very young age, and there was a definite (although she has no conscious memory) emotional delay/reaction that took time to heal - the first time she cuddled into me when in a busy room is a moment that will stay with me forever.
I should also say that we went out on something of a limb, and did it our way (SW go heavy on the need to sort of 'remind' them theyre adopted). We're parents whose DD came into our family in a different way; beyond that we've brought her up as we wouldve a birth child. She knows she is adopted, she knows most of her background, however its never been made a defining feature. She owns it, she calls the shots. We have no contact with birth family, she knows first names and some background, theres a more in depth information link if/when she wants to know more about them.
